I love my fold, but it has some design deficiency's that effect reliability. The biggest problem is having the controller locked up inside the frame with no ventilation. This makes the controller get very hot when using lot of power, and causes failures.
Be aware that Sondors controllers, and display's are protocol protected, which means neither part will work with aftermarket controllers, or display's. The work around for this problem is to replace both parts at the same time.
These aftermarket parts will replace the stock controller, and display.

While you're at it, it would be a good idea to move the controller to outside of the frame, but it requires a lot of extra work.
